A source close to the family told the New York Daily News, "The waking-up process has begun and will take until Tuesday. There is real concern that the part of the brain that controls motor skills may have been compromised, leaving her as either a vegetable or in a wheelchair."

Rivers was placed in the medically induced coma in order to help stabilize her vital signs, and as of yesterday, she was reportedly breathing on life support.

And while the extent of the possible damage done to Joan will not be known until she is fully out of the coma, a source indicates that the family is angry, and might consider legal action against the clinic where Joan had the procedure done. He/she says, "Shock and upset is turning to anger, and they are looking for someone to blame."

It sounds like we may not hear any more updates on Rivers' status until the middle of this week at best, when there is more information on whether or not she's expected to recover.

Our thoughts and prayers go out to Melissa and the rest of Joan's family during this horrible, scary time.
